Application filed March 11, 1913. Serial No. 753,540.

To all whom t may concern.'

Be it known that I, `EDGAR W. ALLEN, a citizen of the United States, residing at San Jose, Santa Clara county, California, have invented new and uset'ul Improvements in Coin-Controlled Locking Mechanism, (see Patent N o. 988,059, issued to me, Encan W. ALLEN, March 28, 1911,) of which the following is a specification.

This invention relates to a coin controlled lock which may be made of any suitable materials best suited to the construction to which it is to be attached.

My further object is to provide a simple and durable automatic locking device which may be constructed to admit a coin of any dimension, by which it can be controlled, the coin or piece of metal acting as a key to disengage the locking lever from the bar locked.

This invention consists in the combination of parts more fully described by reference to the accompanying drawings in which- Figure l is a front view showing position of the levers and bars when locked, also position of the coin ready to contact the lock.- ing lever. Fig. 2 is an upright section of each member of the lock, showing the bars AMA. to be locked. Fig. 3 shows a crosssection of the coin carrier and race at BB, Fig. 1 in combination with the casing CC. Fig. 4 shows asection` of the bars, locking lever 2 and spring latch 4, and contacting bar 9 as held in the slot D Fig. 1.

In the drawings C-C indicates the casing which is slotted at Dto receive the bars to be locked.

The locking lever 2 is held by a pivot 3 Fig. 1, which is set in a boss raised to any desired height in the casing C. The governor or latch lever 4 Fig. 1, is also held on the pivot 5 which is set in a boss the same as the locking lever 2. To the latch lever 4 is attached two tongue steel springs 6 and 7 secured by two screws 5'., these two springs are held under tension by the latch lever 4 which is forced into position by the contacting bar 9 which may be applied b y any means whatever, and retained until freed by the action of a coin onthe locking lever 2. The spring 7 acts against the end of the coin carrier 8 Fig. 3 and is so adjusted that it will return the carrier 8 to its normal position as shown at B-B Fig. l and will allow free action of the coin carrier 8 without moving the locking lever 2 when (the key) a coin 10 is not in place.

The coin carrier 8 is so constructed that when a coin 10 is in. place (as shown at B-I) it can be pushed forward by the finger at E and so engage the coin 10 bc-` tween the shoulder 15 in the coin carrier 8 and t-he locking lever 2 Fig. 8, until the locking lever 2 is forced into the position shown by dotted lines 2 when the contacting bar 9 can be thrown out of the slot D by any force in use when all levers will be tree and the coin will drop through an opening 10 into the receptacle 11.

The looking lever 2 is weighted at 2" sulficient to normally retain the latchlever 4 in the positionshown by dotted line 4 Fig. 1, ready for the attack by a bar 9 to be locked whichV automatically forces the locking levers into position to receive and hold the coin. I provide a race 12 Fig. 1 to guide the coin 10 into the carrier S, the coin to be inserted in slot 15 Fig. 2 and held in place by an auxiliary cover 14. Fig. 3 which extends across the face at B-B and upward covering the race 12. The coin carrier 8 is encircled and held in position and guided by an extra boss 16 Fig. 2 set through the casing C and retained by ascrew 17, Fig. 1.

Having thus described my invention, what l I claim and desire to secure by Letters Pat` ent is:

1. In a coin-controlled mechanism in combination with an element to be locked, a reciprocal coin carrier having a coin-receiv ing recess on one face thereof, a locking lever to lock said element having its lower end extending into said recess so as to close the outer end of the latter, a latch lever pivoted to one side of said locking lever, and a pair of independently acting flat springs connected to said latch lever, said springs bination with an `element to be locked, a

reciprocal coin-carrier having a coin receiving,` slot, a locking lever to lock said element having a part extending into said slot, a latch lever, and a pair of independently acting spring elements connected to said latch lever one of Which elements engages the coin carrier and the other of Which elements engages the locking lever, said latch lever being` moved to a position Where its said springs tension the coin carrier and the locl ing lever by the movement oi said element to .locking position.

3. ln a coin-controlled mechanism, a reciprocal coin-carrier, locking means having a part which is disposed adjacent `to the coin-carrier so as to provide a space between locking position.
